School and law enforcement officials are reminding everyone that such actions simply won't be tolerated, especially in the wake of the violence in Connecticut.

The suspect is a 15-year-old student, but police said he helped spread a vicious and frightening rumor at an area high school.

Police and school officials said the post sparked a wave of fear that swept over Jeffersonville High School and eventually led to the filing of felony charges against the teen.

"The message presented through social media was such that in and of itself, it created an environment of great concern," said Greater Clark Schools' Superintendent Andrew Melin.

Officials would not comment on exactly what the student's Facebook post said. They would only say that it referred to some sort of violent act that was supposed to occur at the high school Friday.

Police said it was completely untrue and that the rumored violence was never going to happen.

"We found no means that he had available to him to carry out any type of violence at the school," said Jeffersonville Police Detective Todd Hollis.

Still, just the threat of such action is enough for police to take action.

On Tuesday morning, the teen was arrested and charged with two felonies; intimidation and terroristic deception.

Police said that's how they will handle all such situations in the future.

"Anyone who makes any threat against the safety of our schools will be dealt with swiftly and to the fullest extent of the law," said Hollis.

"This is very serious business. Social media is out there, we know that, but our students need to understand the incredible power social media has and using social media has its consequences," said Melin.

Their broader message could have been delivered by virtually any superintendent in the country right now.

"We want our students and our staff and our parents to know that we are 100 percent committed to doing everything in our power to make sure that our school buildings are as safe as possible," said Melin.

Greater Clark Schools have already implemented some new safety measures.

Parents are now being asked to call their child's school in advance if they plan on visiting and may still be asked to present identification when they arrive.

Classroom doors are being closed and locked while classes are in session.

Officials said camera and buzzer entry systems for visitor access should be installed at all schools by the time students return from winter break.

Clarksville police said they have heard about everything from possible gun violence to bomb threats at several schools in the area. Most of these claims have turned out to be false.

In Louisville, Pleasure Ridge Park High School was on increased security after a threat Tuesday morning.

“They were saying, like, ‘I don’t want to get shot and I want to go home,’” said PRP freshman Jessika Roller.

The scare was big enough for some PRP students to head straight back home.

“Well, I wanted her to pick me up because I just didn’t feel safe at school,” Roller said.

“I’m taking my son home. He’s going home for the rest of the day, where he’s going to be safe,” said PRP parent Melissa Murrell.

It was a big response, triggered by a tiny rumor.

A PRP student’s parent heard secondhand that someone was going to bring a gun to school with intentions to harm. Police and K-9s did a sweep of the school, but the claim turned out to be nothing.

“Our security forces don’t believe that there is any credibility to this rumor but, again, out of an abundance of caution, trying to assure parents that PRP is a safe place to be for students,” JCPS spokesman Ben Jackey said.

JCPS said three students were disciplined in connection to Tuesday's incident: one student for making the claim they saw a weapon on campus, and two others for inappropriate comment made about the situation.

Clarksville's police chief said it's the same situation on the other side of the river. Clarksville Middle and High School, as well as Silver Creek High and Jeffersonville High have all had rumors circulate threatening violence to students.

School officials and police responded every threat.

“Nobody can actually pinpoint the source where it originated from,” said Clarksville Police Chief Mark Palmer.

Palmer said chasing down every claim is a time-consuming effort.

“Unfortunately, it takes away from the rest of our duties here to have to keep these rumors from spreading,” he said.

However, it is something to be expected after a shooting like the one in Connecticut.

“Like the Columbine shooting that occurred, it was similar during that time period, threats rumors started coming through,” Palmer said. “Even though the threat is not real, the fear is real and that’s what we're looking at here.”

On Monday, North Bullitt High School said officials also responded to claims like this.
